§ 200. If a captured enemy vessel carries goods consigned by enemy subjects to subjects of neutral States, or to subjects of the belligerent whose forces captured the vessel, they may not be appropriated, provided the consignee can prove that he is the owner. As regards such goods found on captured enemy merchantmen as are consigned to enemy subjects but have been sold in transitu to subjects of neutral States, no unanimous practice of the different States is in existence. The subject of goods sold in transitu must—in the same way as the question of transfer of enemy vessels—be considered as forming part of the larger question of enemy character. It has, for this reason, been treated above, § 92.
IV VIOLENCE AGAINST ENEMY PERSONS
See the literature quoted above at the commencement of § [107]. See also Bonfils, Nos. 1273-12733
Violence against Combatants.
§ 201. As regards killing and wounding combatants in sea warfare and the means used for the purpose, customary rules of International Law are in existence according to which only those combatants may be killed or wounded who are able and willing to fight or who resist capture. Men disabled by sickness or wounds, or such men as lay down arms and surrender or do not resist capture, must be given quarter, except in a case of imperative necessity or of reprisals. Poison, and such arms, projectiles, and materials as cause unnecessary injury, are prohibited, as is also killing and wounding in a treacherous way.[402] The Declaration of St. Petersburg[403] and the Hague Declaration prohibiting the use of expanding (Dum-Dum)[404] bullets, apply to sea warfare as well as to land warfare, as also do the Hague Declarations concerning projectiles and explosives launched from balloons, and projectiles diffusing asphyxiating or deleterious gases.[405]
[402] See the corresponding rules for warfare on land, which are discussed above in §§ 108-110. See also U.S. Naval War Code, article 3.
[405] See above, §§ [113] and [114].
All combatants, and also all officers and members of the crews of captured merchantmen, could formerly[406] be made prisoners of war. According to articles 5 to 7 of Convention XI. of the Second Peace Conference—see above in § [85]—such members of the crews as are subjects of neutral States may never be made prisoners of war; but the captain, officers, and members of the crews who are enemy subjects, and, further, the captain and officers who are subjects of neutral States may be made prisoners of war in case they refuse to be released on parole. As soon as such prisoners are landed, their treatment falls under articles 4-20 of the Hague Regulations; but as long as they are on board, the old customary rule of International Law, that prisoners must be treated humanely,[407] and not like convicts, must be complied with. The Hague Convention for the adaptation of the Geneva Convention to sea warfare enacts, however, some particular rules concerning the shipwrecked, the wounded, and the sick who, through falling into the hands of the enemy, become prisoners of war.[408]
